Winter trail and panorama at Lily Lake in Rocky Mountain National Park. Composite of five images taken with a Nikon D3 camera and 24-70 mm f/2.8 lens (ISO 200, 24 mm, f/16, 1/160 sec). Raw images processed with Capture One Pro and the composite generated using AutoPano Giga Pro. The jags in the contrails unfortunately show that the upper winds were strong while taking the five images.
